WHALE-OIL-REFINERY VESSEL.

Application filed February 17, 1927, Serial No. 169,033, and in Norway February 26, 1926'.

In whale oil refinery vessels, especially those which are used in large seas or on the oceans, the roughness of the water may prevent the bringing on board and the fienching of the whale. This is especially the case in that type of whale oil refinery vessels, in which the whale is taken on board or is brought into docks. sluices or the like, provided in the forepart or the afterpart of the vessel.

These drawbacks are avoided by the present invention, which is especially characterized thereby, that the dock or docks are provided at the side or sides of the longitudinal middle line of the vessel.

In this way it is possible to take in and treat two whales at the same time. while in addition the housing and the flenching of the whales are easier on account of the less movement of the vessel midship. By running of the sea these docks will also not be drained, whereby damage to the vessel and the equipments by knocks of the body of the whale against the bottom of the dock or the floaters, carrying the same, is avoided.

The invention is illustrated in an executional form in the accompanying drawing, in which:

Figure 1 shows a whale oil refinery vessel with side docks in a vertical section.

Figure 2 is a plan view of the vessel, the upper deck on the port side being removed.

Figure 3 is a section at line III-III in Figure 2 in enlarged scale.

Figure 4 is a section at line IV-IV in Figure 2 in enlarged scale.

1 is a whale oil refinery vessel according to the invention. At each side of the forepart 2 of the vessel a sluice or dock -3 for a whale is provided. Rearwardlv of the docks the vessel is partially contracted, as indicated by 4 in Figure 4:, so that the whale may be guided alongthe side of thevessel through ports -56- into the dock.

These ports may be swung either one outwards and one inwards or both outwards or inwards. They may be opened and closed by vertical or horizontal screws and bolts or both kinds.

If wanted, for stiffening there can also be provided watertight sluice ports 7, which may be raised or lowered in closely fitting frames. The whale is kept floating in the dock, and the fienching and cutting take place in the same, and the pieces are conveyed up to the deck along a fixed slip 8 at the front of the dock and by an adjustable slip at the back of the dock (not shown in the drawing). Further the necessary hoisting machinery is provided in such a manner, that the pieces may be hoisted up without use of a slip. In the longitudinal bulk heads 9- ports 10- are provided, so that the pieces may be treated as well on the deck -11 as on the deck 12-.

Then the deck ports are closed, it wanted the docks may be drained and filled by means of the pumping machinery.

In a whale oil refinery vessel according to the invention the propeller shaft is placed in the longitudinal middle line plane, and the vessel accordingly need not be provided with more than one propellingmachinery unit. As the whale is hauled in along the side of the vessel, it is not risked that the hauling mechanism and its parts come into engagement with the propeller, and the vessel may therefore easily be kept against the wind. By contraction of the vessel only under the deck the area of the deck is not reduced.

On the outer railing of the vessel detachible breakwaters may be provided, indicated The upper part of the docks may be quite open, but there may also be provided springers 14 and deck springers 15 in the lower deck orboth decks for the flenchers. may also be provided openings 16 eventually with coamings 17- so that battenable hatches are formed and the docks may then be used as cargo spaces.

Alterations of the construction may be made without departing from the scope of the invention. Thus when the port is placed in the front of the dock the forepart of the vessel may be contracted instead of the afterpart. as shown.

What I claim is 1. In a whaling vessel. chambers forming docks provided at the sides of the longitudinal vertical plane of the vessel and adapted to be opened to the sea to admit and hold a whale, and the after part of the vessel being contracted in order to facilitate the hauling ofa whale into the adiacent chambers.

In the upper deck 11 there 2. A whaling vessel including a hull provided with superposed decks, chambers forming docks provided at the sides of the longitudinal vertical plane of the hull and extending practically from the middle part of the hull to the forward end thereof, said chambers intersecting and communicating with the decks doors provided adjacent the lower part of the chambers adapted to be opened to the sea to permit of the admission of a whale, 5 and Water tight sluice-ports adjacent the doors, substantially as and for the purposes set forth.

3. A whaling vessel as claimed in claim 2,

wherein fixed slips are arranged between the bottoms of the chambers and the adjacent deck, and wherein the after part of the vessel is contracted in order to facilitate the hauling' oi a whale into the adjacent chamber.

In testimony whereof I have signed my name to this specification.
